Conventional gravel pack completions often reduce the wells productivity by increasing the completion skin. This paper describes a methodology backed by a systematic technique to predict the necessary drawdown, frac length, and conductivity to prevent formation failure and remove the completion damage. This method enables the engineer to optimize the fracture dimensions while obtaining the necessary decrease in drawdown near wellbore that would cause the unpacked perforation to fail. This technique will greatly reduce the chance for formation failure and improve the well performance without the need to gravel pack.

The perception of danger in HRI settings has become increasingly important as interactions between robots and humans become more commonplace. Previously, a perceived danger scale was developed and validated. Here, we shortened this scale to create the Perceived Danger-Short Form (PD-SF) scale. Experiment 1 used pre-existing data and standard procedures to shorten the scale from 12 items to 4. Experiment 2 validated the short form in a new experiment where participants observed images of robots holding kitchen items of varying levels of danger in close proximity to a human. PD-SF was able to capture differences across the kitchen items. Results from both experiments indicate that PD-SF is a reliable and psychometrically valid measure of perceived danger in HRI contexts.

ABSTRACTBackgroundPartnering with community leaders, we sought to address ongoing diagnostic testing needs in underserved neighborhoods and evaluate whether a saliva-based mobile testing program could help overcome barriers to testing for uninsured and low-income individuals. This is critical as many lack a primary care provider, cannot access reliable health information, or have limited financial resources.MethodsFree saliva-based, SARS-CoV-2 diagnostic testing was offered at 123 local community events in Connecticut, between June 2023 to July 2024. The SalivaDirect extraction-free RT-qPCR protocol was run on a CLIA licensed van operated by Yale Pathology Labs under FDA Emergency Use Authorization. Testing locations were identified and advertised in partnership with the community. Patient perspectives on approachability, convenience, and usefulness of mobile testing were recorded via REDcap.ResultsApproximately 100 local contacts informed the mobile testing model. Overall, 1,428 individuals participated, with 838 completing a testing experience survey. Of these, 54% identified as Black, Indigenous, People of Color; 59% reported annual household income less than $25,000; 31% were uninsured. Test results were reported in an average 3.1 hours, 48 positive samples were identified. Test takers agreed it was easy to access the van (74%) and felt comfortable (75%); 29% received their first COVID-19 test at the van; 48% were unaware of alternate testing; 44% reported difficulty accessing health care; and 49% identified transportation as a challenge.ConclusionsThis study demonstrated the positive impact mobile testing could have for overcoming barriers to accessing healthcare, and its potential to serve as a framework for managing and responding to future public health needs.

Early fruit drop is one of the most important diseases that usually decrease the production of mango trees in Egypt. The typical symptoms of early fruit drop were observed on four surveyed Egyptian mango cultivars (Hindy, Ewais, Keitt, and Montakhab El-Qanater) during 2022 and 2023 seasons. Among these cultivars, Montakhab El-Qanater recorded the highest percentage of fruit drop while Ewais showed the lowest percentage in both inspected seasons. Fusarium moniliforme Sh., Lasiodiplodia theobromae Pat. and Alternaria alternata (Fr.)Keissler, were isolated from early dropped fruits of inspected cultivars and recorded the highest frequencies, respectively. Pathogenicity test showed that isolated fungi were able to induce the early fruit drop disease with typical symptoms. Montakhab El-Qanater cv. was the most susceptible for fungal infection compared to Ewais cv. Infection with each of F. moniliforme, and L. theobromae was inherent to the high percentage of fruit drop compared with A. alternata. In vitro, the efficacy of five commercial agrochemical products (Bellis, Craft, Dovex, Score and Tekto) was evaluated on the isolated fungi. Generally, the linear growth of any of the isolated fungi was inhibited with 0.5ml/L of Score, 0.5g/L of Bellis and 1ml/L of Tekto, respectively. In vivo, the treatment with Score (50ml/100L) significantly decreased early fruit drop during the two experimental seasons on Montakhab El-Qanater and Ewais cultivars. The lowest efficacy was obtained with Craft (40ml/100L) and Dovex (25ml/100L). The physiological effects of the evaluated products were measured on total phenolic content and enzymatic activities of chitinase (CHT), peroxidase (PO) and polyphenol oxidase (PPO) in leave extract of Montakhab El-Qanater and Ewais cultivars. The total phenolic content and enzymatic activities were significantly promoted in both cultivars with the treatments of the evaluated chemicals. The highest values of total phenolic content in both cultivars were detected with Score, Bellis and Tekto, respectively. While, the greatest activity of measured enzymes was revealed with Bellis, Score and Tekto, respectively.

El presente artículo explora la importancia de la Comunidad Social Deportiva como un espacio que fusiona la labor de los clubes de barrio y de pueblos en Argentina resaltando su rol clave en la promoción de una sociedad activa y en la mejora de la calidad de vida.

Despite proven effectiveness in reducing motorist crashes involving wildlife, systematic inclusion of wildlife-mitigation measures during highway planning and projects continues to vary by jurisdiction in the United States and Canada. Some agencies invest significant resources to reduce wildlife–vehicle collisions (WVCs), while others invest few or no resources. Various factors have been identified as relevant in explaining why some jurisdictions are more proactive than others in addressing WVCs. This analysis builds on existing literature by comparing select legal decisions in the United States and Canada regarding public authority liability for failures to remediate known WVC hot spots, with the goal of assessing the potential role of liability in creating incentives for government decision makers to systematically address motorist crashes involving animals.

A partir do livro mais atual de Habermas, o artigo busca compreender como o processo comunicacional de justificação recíproca pode alimentar uma comunicação pública capaz de articular a formação do sujeito político autônomo ao processo cooperativo de busca pela definição do interesse público. Habermas nos convida a não deixar de lado nossas experiências e o processo de florescimento de nossa autocompreensão, mas a articular a experiência singular com a busca pelo ponto de vista moral necessário à justificação recíproca. Diante da devastação das vidas e das sociedades governadas pelo neoliberalismo, diante do aumento dos ódios, do repúdio às diferenças, dos preconceitos de gênero, classe e raça e da valorização de políticas individualistas e meritocráticas, pensar o papel das esferas públicas como processo central às democracias deliberativas requer uma comunicação pública amparada pela reflexividade uma rede de esferas públicas que permite a todos os participantes a chance de reconsiderar e redefinir constantemente seu horizonte partilhado de experimentação e agência coletiva.
